A Domino Revelation occurs when the revelation of a previously hidden truth leads to another revelation, then another, like the knocking over of dominoes.

Often evoked in {{fantasy}} works, where the revelation that one mythological or legendary species exists leads to finding out that many more also do, and works featuring conspiracy theories, where finding the shadowy figures behind a seemingly minor crime opens up a vista of sinister plots all emanating from the same source. In {{romance}}, one confession can often lead the way to one or several more.

It gets a good bit of use in UrbanFantasy and SteamPunk works as well.

AllMythsAreTrue is a common end result when all dominoes have fallen. May overlap with TheMasquerade or TheConspiracy where the protagonist is introduced to their secrets. Compare IfJesusThenAliens. Contrast ArbitrarySkepticism, when there are further paranormal phenomena that are often real, but not believed by the skeptical characters.----!!Examples:

[[folder:Anime and Manga]]* ''Anime/PuellaMagiMadokaMagica'' does this with {{Awful Truth}}s. In the wake of [[spoiler:Mami's death]], Kyouko's appearance shows that few magical girls are as altruistic as [[spoiler:Mami]] was. This leads to Sayaka's confrontation with Kyouko on the bridge, where it's revealed that [[spoiler:Soul Gems literally [[OurLichesAreDifferent contain the soul of a magical girl]]]]. This, in turn, leads Sayaka to [[spoiler:fall into despair, corrupting her Soul Gem and revealing that a corrupted Soul Gem doesn't break or disappear, but instead turns into a Grief Seed]], a revelation which prompts Kyubey to explain to Madoka [[spoiler:the true nature of the magical girl system]]. Additionally, the process of [[spoiler:Sayaka falling into despair]] leads to a chain of events resulting in the revelation that [[spoiler:Homura has some form of time travel/timeline changing ability]]. Basically, the revelations show piece-by-piece how the inner workings of the fairly cliche-looking premise are actually [[DarkerAndEdgier terrible, terrible things]].* ''Anime/ValvraveTheLiberator'' starts with the revelation that the school in the supposedly peaceful nation of JIOR was actually hiding the titular superweapons. [[spoiler: Investigating this, L-elf discovers that the teachers and all of the other adults on the module were actually military officials, and only the students were kept in the dark about it. From this, he eventually gets to the revelation that the entire module was made for the development of the Valvraves and their power source.]]* ''Manga/OnePiece'' is full of this, where most of the world's hidden mysteries are inter-connected.[[/folder]]

[[folder: Comics]]* ''ComicBook/BeastsOfBurden'': Vampires, zombies, ghosts, and other things show up.* ''Comicbook/WerewolfByNight'': Werewolves aren't the only supernatural thing out there - there are also weretigers, vampire, demons, and other superheroes!* ''ComicBook/{{Legion of Super-Heroes}}'': In the Earthwar Saga storyline, the attacks on Earth by the Resource Raiders turns out to be the advance guard of an attack by the Klingonesque [[ScaryDogmaticAliens Khunds]]. Whose leader is secretly being controlled by the shadowy Dark Circle. Who are secretly being commanded by EvilSorcerer Mordru.

[[folder:Film]]* In the [[Film/PiratesOfTheCaribbeanTheCurseOfTheBlackPearl first]] ''Franchise/PiratesOfTheCaribbean'' movie, Elizabeth Swann finds out that cursed pirates are real. The next four movies confirm the reality of [[AllMythsAreTrue pretty much every myth or legend ever told concerning the sea]].[[/folder]]

[[folder: Literature]]* ''Literature/CalLeandros'': Elves that call themselves Auphe are first introduced followed by a revelation of hidden monsters like Banshee and Trolls in the world amongst humans.* ''Literature/JaneYellowrock'': The main hereon is a skin-walker, she fights vampires and has a witch for a best friend.* ''Literature/MercyThompson'': in this series we meet werewolves, vampires, and witches right off the bat followed by ghosts, demons, and eventually shamans and mages of ill repute.* ''Literature/HarryPotter'': Witches and wizards, giants, dragons, giant magic spiders... the list is a little long for this series. * ''Literature/KittyNorville'': Well same thing we meet werewolves first, then learn of vampires, werepanthers, magic users, psychics, and other types of the supernatural ilk.* ''Literature/TheHollows'': Witches and vampires exist, so why not ghosts, demons, and other such creatures?* ''Literature/TheOtherworld'': the woman of the other world are all sorts of supernatural types. We have witches, werewolves, nercourgists, half-demons, and angels. Of course this trope is in full effect.* ''Literature/TheSookieStackhouseMysteries'': After the vampires have their coming out party we meet shifters, werewolves, weretigers, fairies, and several other supernaturals.* ''Literature/SoulScreamers'': If the fact the main character is a banshee isn't enough, there are reapers, angels, and demons all hell bent on human souls.* ''Literature/{{Twilight}}'': First come the vampires. Then come the werewolves. * ''Literature/PercyJacksonAndTheOlympians'': Satyrs, the Minotaur, Greek gods, centaurs, nymphs... Again, the list is rather long. ** The various sequel series take this to eleven, with the revelation that the Norse, Roman, and Egyptian pantheons, AND the various monsters and magic that go along with them, also exist. The existence of Jesus is also hinted at. * ''Literature/TheDresdenFiles'': Although protagonist Harry is himself a wizard, his knowledge of the supernatural world is often rather lacking, leading to [[FantasyKitchenSink many]] revelations throughout the series that he learns of at the same time as the reader.[[/folder]]

[[folder:Live Action TV]]* ''Series/{{Charmed}}'': First we learn of witches and demons, then angels, spirits, fairies, and a whole mess of critters come crawling/teleporting/orbing/shimmering out of the woodwork.* ''Series/{{Fringe}}'': Similar to ''The X-Files'' with aliens, mind control, and other weird things being revealed.* ''Series/LostGirl'': All supernatural creatures exist, some are [[TheFairFolk True Fae]] others just call themselves fae and are in fact Succubi, Spirits, Werewolves, and all manner of other magical creatures.* ''Series/{{Supernatural}}'': Dean and Sam are hunters. They fight demons, astral creations, angry angels, pagan gods, ghosts, etc.* ''Series/TheXFiles'': Earliest TV example of this trope; from MonsterofTheWeek to aliens in the basement with werewolves, wild men, demonic beings, and eventually BodyHorror and evil spirits... this series had it all.* ''Series/TrueBlood'': Vampires first, shapeshifters, then goddesses, werewolves, fae, werepanthers, and witches.* ''Series/TheVampireDiaries'': Again vampires first then we learn that witches and werewolves also exist.* ''Series/MyBabysittersAVampire'': The main characters have a babysitter that is a vampire. They also find out that one of them can see the future and that witches exist.[[/folder]]

[[folder: Video Games]]* ''VideoGame/{{Persona}}'': Well, it's more FantasyKitchenSink at times. Spirits (demons in Japanese) exist, but that's merely the catch-all term for supernaturals. And they ALL are very real projections of one's psyche.* ''ShinMegamiTenseiI'': Angels, demons, and god....yes, it's all real.[[/folder]]

[[folder: Web Original]]* ''Series/{{Noob}}'' has had this happen a few times:** Season 3 WhamEpisode and aftermath: [[spoiler: Fantöm's avatar has been illegally enhanced all along. By the game's creators themselves, who put the blame on Fantöm (who knew nothing) the second the secret is made public. It's Master Zen who revealed the fact and the protagonist's new recruit Nazetrîme has been working for him all along]].** Late Season 5: [[spoiler:Judge Dead is Tenshirock's son and the person he's actually trying to drive away from MMORPG. On a side note, Teshirock's wife/Judge Dead's mother is dead and Spectre has the condition that is implied to have caused her death. Tenshirock figured it out and convinced him to retire a few years ago. This is the reason Spectre was retired until Season 3]].** ''Film/NoobLaQueteLegendaire'': [[spoiler:Sparadrap's father is not a priest as he's been telling everyone, but a mafia big wig passing as one. Elyx, Master Zen's second in command, may be his mother... or Ystos'... or that of a third son of his father's. His father forgot and Elyx can't help because she got a lobotomy between giving birth and the present day.]][[/folder]]

[[folder: Western Animation]]* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'': Just full of all kinds of magical creatures of all styles shapes and sizes. Most of them talk, cast spells, and have civilizations.* The season one finale of ''WesternAnimation/GravityFalls'': That room behind the vending machine is finally shown. Then Stan takes Journal #1 out of a desk - ''he's'' had it since the show began. ''Then'' he declares, "Finally, after so many years... I have them all." Stan knows a ''lot'' more about the town than he's let on.[[/folder]]----
